Buncheong ceramic composition and manufacturing method thereof

The present invention relates to a powdered cheong mixed body composition and a method for producing the same.

The content described in this section merely provides background information on the present invention and does not constitute the prior art.

In general, ceramics have been used in a certain composition ratio with kaolin, including feldspar and silica as raw materials. Porcelain holdings can be largely divided into white porcelain, buncheong, and celadon, and in addition to this, combined clay, sancheong, pottery, and porcelain are widely used.

Among these ceramics, buncheong soil can be said to be the soil that makes buncheong ware. Buncheong-sagi is a porcelain in the early Joseon Dynasty in which the surface was made of white clay on top of gray or gray black. It is an abbreviation of the make-up-hoe-cheongsagi, and this make-up technique shows the process of transitioning to white porcelain by covering the surface of the bowl with white clay and displaying patterns. These buncheong ware were transformed and developed from celadon at the end of Goryeo, and were produced for a long time of about 200 years in the 15th and 6th centuries.

However, the conventional buncheong soil, the raw material of the buncheong ware, has a problem that the work breaks well even after firing the chaebol because the strength is weak. In addition, the dust cleaning paper has a dark brown color when sintered, so it is difficult to give an overall elegant and luxurious feeling, and when it is produced, there is a problem that it does not match well with the color of the work.

Accordingly, the present inventors have repeatedly conducted extensive research to develop powder cleaning materials that can make use of the luxurious natural beauty, and as a result, mixing white porcelain and acid cleaning materials in powder cleaning materials has high strength and has a color that matches the work well. It came to completion.

Ceramics manufactured using natural celadon base oil in the prior art (Patent No. 0885391) used materials including sancheong earth, buncheong earth, and celadon clay, but in relation to the strength and color of the material according to the mixing ratio No advanced content is disclosed.

An object of the present invention is to provide a powdery green mixed body composition having a high strength and a color capable of utilizing a luxurious natural beauty, and a method for producing the same.

As shown in Table 1 above, the No. 1 mixed body composition includes only powder cleaning. This is using a conventional powder cleaning composition. Compositions No. 2 to No. 6 relate to the powdered powder mixture according to the present invention. The content ratio of the powder cleaning paper was fixed at 55% by weight based on the total weight of the composition, and the experiment was carried out by adjusting the mixing ratio of the white porcelain paper and the acid cleaning paper.

Bending strength measurement experiment

Table 2 below summarizes the experimental results of measuring the bending strength by making 6 test pieces for each composition using the above compositions 1 to 6. Here, the experimental conditions were carried out within a range in which the substrate can maintain plasticity. The range of maintaining plasticity may mean that after the test piece is manufactured using the substrate, the test piece is hardened and the shape cannot be changed even if an external force is applied any more. The firing temperature was performed at 1250°C, and each test piece was prepared by unglazing all. However, if necessary, you can proceed from unglazed to chaebol-grilled.

As described in Tables 2 to 7 above, six specimens using each composition from No. 1 to No. 6 were prepared to each have a width, thickness, length and load within a certain range to measure the bending strength, and the bending strength. The average value of was derived.

As shown in Tables 2 to 7 above, it can be seen that the correction value of the bending strength of the six types of compositions is significantly increased to 519 kgf/cm ² from the fourth composition shown in Table 5. That is, in the case of compositions 4 to 6, it can be seen that the bending strength is significantly increased compared to the conventional one. Therefore, it can be seen that in the case of 55% by weight of powder cleaning paper, 25 to 35% by weight of white porcelain paper, and 10% by weight of acid cleaning paper to 20% by weight based on the total weight of the composition, it can be seen that it shows significant characteristics in its bending strength.

In addition, the test piece having the highest bending strength was made of composition No. 6. As shown in Table 7 above, the average value and correction value of the bending strength of the composition 6 were derived the highest. Composition No. 6 is characterized in that it is 55% by weight of powder cleaning paper, 35% by weight of white porcelain paper, and 10% by weight of acid cleaning paper based on the total weight of the composition. That is, the weight ratio of the powder cleaning paper, white porcelain paper, and acid cleaning paper, which are components included in the composition, is 11:7:2.

The six test pieces prepared using the No. 6 composition may be prepared to fall within the range of 4.96 to 5.47 mm in width, 50 mm in length, and 4.54 to 4.87 mm in height. The bending strength of the six test pieces prepared based on the composition No. 6 was 438 to 630 kgf/cm ² Can be In addition, the average value of the bending strength of these six specimens is 510 kgf/cm ² , and the correction value considering the standard deviation is 536 kgf/cm ² .

Compare your own color

Referring to FIG. 1, FIG. 1 is a photograph of a test piece made using the six types of compositions in Table 1 above. However, only two test pieces (for example, 1-1, 1-2) with the first number for each composition were arranged and photographed. Referring to the drawings, it can be seen that each test piece was split in half, which was split in the course of the experiment measuring the bending strength.

Comparing the colors of the compositions 1 to 6, it can be seen that in the case of No. 1, it was a test piece containing only minute cleaning, which was close to brown and had a yellow color. However, as the content ratio of white porcelain paper increases and the content ratio of acid cleaning paper decreases, the brown and yellow colors gradually disappear, and it can be seen that the color is light gray and blue gray. In the case of No. 6, when compared to the other compositions No. 1 to No. 5, a lighter gray-blue color is expressed. That is, it can be seen that the color of the test piece of composition 6 is gray-blue, which expresses a luxurious natural beauty that goes well with the work.
